OIL BURNER Filed Nov. 2, 1928 J. L. RICKETTS ET AL 2 SheetsSheet 2 CITPatented May 31, 1932 UNITED STATES PATENT OFFICE JOHN L. RIGKETTS .ANDCHARLES F. DENGLER, OF PHILADELPHIA, PENNSYLVANIA OIL BURNER Applicationfiled November 2, 1928.

This invention relates to oil burners and more particularly to theconstruction of that type of oil burner employing nozzles in theformation or partial formation of an inflammable mixture and has for animportant objcct thereof the provision of a burner of this characterwherein the maintenance of the nozzles in a clean operative condition ismaterially facilitated.

A more specific object of the invention is the provision in combinationwith an oil burner including a plurality of fuel supply nozzles ofcleaners for said nozzles and a common actuating means for the cleanersso constructed that simultaneous actuation of the cleaners is avoidedthereby preventing any danger of accidental extinguishing of the burnerwhen in operation.

A still further object of the invention is the production of anapparatus of this character which may be very readily and cheaplymanufactured which will be durable and efiicient in service and ageneral improvement in the art.

These and other objects we attain by the construction shown in theaccompanying drawings wherein, for the purpose of illustration, we haveshown a preferred embodiment of our invention and wherein:

Fig. l is a vertical sectional view through a furnace having an oilburner constructed in accordance with our invention disposed therein;

Fig. 2 is a plan view of the oil burner;

Fig. 3 is a transverse sectional view there through; and V Fig. 4 is afragmentary front elevation illustrating the mounting of the controldevice for the cleaners. v

Referring now more particularly to the drawings, the burner 7constructed in accordance with our invention is preferably locatedwithin the ash-pit of an ordinary boiler furnace l and is supported froma low pressure boiler 8 from which steam is passed upwardly by means ofa pipe 9 to the burner to intermingle, in a manner hereinafter morefully described, with oil from a pipe 10. The low pressure boiler may besupplied with water through piping 11 and is also supplied with SerialNo. 316,825.

a gas line 13 operating a Bunsen burner or the like indicated at 13-athrough which the boiler is heated. The boiler 8 may be adjustablysupported upon standards 142 143 and 144 which may likewise serve tosupport a series of baffles and 6, the baliies 5 being supported fromthe'baiiies 6 through a central spindle 4. Balflcs 5 and 6 extend intothe fire box 2 of the furnace and serve to prevent too rapid rise of theheat from the burner. The oil burner 7 comprises a body B upon which aresupported opposed nozzles 22 and 23, these nozzles constituting casingshaving outlet orifices 24 and 25 and being supplied with oil from linethrough branches and 21. The body B has an internal cavity 26constituting a manifold in communication with the steam line 9 which isprovided with outlet orifices 27 and 28 de-' livering steam transverselyof the orifices 24 and 25. A pilot 29 supplied with gas from the line 12is employed to ignite the combustible mixture formed by the admixture ofair with the sprayed mixture of oil and steam passing upwardly from theorifices 25.

'The numeral 34 generally designates a base which may be convenientlysupported from the body B and which extends to opposite sides of thisbody. Centrally of the base a link 36 is secured to a pivot element 35which pivot element may be extended through the furnace wall andprovided with operating mechanism as hereinafter more fully set forth.By rocking the pivot element, the link 36 may be caused to rock and thusimpart motion to rocker arms 37 and 38 pivoted to the base 34 at 39 and40 respec tively. The arms 41 and 42 of the levers which are remote fromlink 36 are connected at their outer ends to cleaning rods 43 and 44which extend axially through the nozzles 22 and 23 and have their innerends arranged adjacent the orifices 24 and 25 when link 36 is in itsnormal position. The arms 45 and 46 of the rocker arms are connected tocleaning rods 47 and 48 which extend upwardly through the body B andinto the orifices 27 and28. An actuating lever 49 may be secured to therod 35, more clearly shown in Fig. 4 and may have secured to one endthereof a spring 50 for maintaining the actuating lever and thus thelink 36 in a normal position. It will be obvious that by oscillatingthis actuating lever the link 36 may be caused to rock and thus actuaterocker arms 37 and 38 with the result that the cleaning rods 43, 44, 47and -18 Will be impinged against any obstructions in the associatedorifices loosening the same and insuring the clearing ot the orifices.

Attention is also directed to the fact that the operation is such thatthe cleaning rod of but one of the oil nozzles is advanced at a time sothat there is nodanger of cutting off the supply of fuel from bothnozzles so that the burner will be extinguished even momentarily. At thesame time the cleaning operation can he very rapidly carried out.

As the construction employed is obviously J capable of a considerablerange of change and modification without in any manner departing fromthe spirit of our invention, we do not wish .to be understood aslimiting ourselves thereto except as hereinafter claimed.

e claim:

1. In an oil burner, a base, nozzles for one fluid extending upwardlythrough said base, nozzles across the top of said base and .arrangedatan angle to said first mentioned I nozzles for another fluid, a leverpivoted to said base, a plurality of rocker arms pivoted to extensionsfrom said base and connected to said lever, and rods connected to theextremities of the rocker arms and extending through said nozzles,whereby actuation of the lever will cause simultaneous actuation of therocker arms and consequent simultaneous actuation of the rods to cleanthe nozzles.

2. A cleaner for the nozzles of a burner having a frame, comprising alever pivoted to said frame and connected at each end to rocker armsalso pivoted to said frame, each end of each rocker arm opposing theouter end of a nozzle and being connected to a rod exceni-ng through thenozzles of said burner whereby operation of .the lever will causesimultaneous actuation of the rods.

3. In an oil burner, a pair of opposed oil nozzles, a cleaning rodlongitudinally shiftl able in each nozzle, a rocker arm connected toeach cleaning rod, a link connecting the rocker arms and means forrocking said link.
